GATE.

SPECIFICATION forming part of Letters Patent No. 746,871, dated December 15, 1903.

v Application filed May 7, 1903. Serial No. 1565159. (No model.)

To all whom it may concern.-

Be it known that 1, PETER AUGUSTIN Mc- CARVILLE, a citizen of the United States-,residing at Fort Dodge, in the county of Webster and State of Iowa, have invented a new and useful Gate, of which the following is a specification.

This invention relates to gates, and particularly to the vertically-tilting folding-panel type wherein a counterweight is employed for tilting the same.

The principal object of the invention is to provide a simple and efliicient means for normally holding the gate against tilting in such a manner that a release of the holding means will immediately result in a vertical movement being imparted to the gate which will unobstruct the way normally closed thereby.

Another object in View is to provide means for tilting the gate and restoring it to its normal position, which means can be manipulated by an occupant of a vehicle adjacent thereto.

Further objects and advantages of this invention will be apparent as the nature of the invention is better understood by reference to the following description in connection with the accompanying drawings, illustrating the preferred embodiment of my invention, and in which Figure 1 is a perspective view of a gate and operating means constructed in accordance with my invention, and Fig. 2 is a fragmentary view in elevation of a portion of the gate and latch.

The gate consists of a plurality of independent panels 1, pivotally connected to the end battens 2 and 3 by the fastening devices 4. The rear ends of the respective panels are pivoted between two inclined standards 5 and 6, braced by the terminally-engaged vertical posts 7 and 8, each of which is intermediately connected to the standard 5 by cross-bars 9.

The mechanism for operatingthe gate com prises a weighted lever 10, preferably fulcrumed between the two posts 7 and 8 and connected to one of the gate-panels by parallel links 12 and 12, so that the weight 13 on the free end of the lever will have'atend ency to tilt the forward end of the gate until the panels are in a vertical plane.

In order to hold the gate against tilting, I provide a swinging latch 14, which is carried by the lever 10 and carries an antifrictionroller 11, engaging with a latch-strike 15, carried by one of the panels. The strike is provided with a short upwardly-inclined endengaging surface 16 and a surface 17, upwardly inclined at a lesser angle than the angle of inclination of the surface 16. The normal engagement of the latch with the surface 16 of the strike will hold the lever 10 and the panels 1 rigid on their fulcrums, preventing any movement thereof; but when the latch is moved out of engagement with the surface 16 and permitted to move beyond contact therewith by sliding down the top inclined surface 17 the weight will be free to descend and raise the connected end of the lever, so as to tilt the gate in an upwardly-moving direct'i'on until the panels practically assume positions in vertical planes. The latch can be conveniently thrown out of contact with its strike by one of the cords or connections 18, which are terminally attached to the latch, and pass over pulleys 19, carried by standards 20, and overasimilar pulley2l on standards 22. When it is desired to restore the latch to its normal position, one of the cords 23 can be manipulated to effect the desired result. This cord also passes over the pulley 2i and under the pulley 24 on one of the standards 5 at a point below the latch, and said cords are then attached to the latch. A pull on the free end of the cord will exert a downward pull upon the latch, which will cause the roller 11 to ride upon the adjacent panel, depressing the forward ends of the entire series until the gate is in a horizontal plane, when the roller will ride up over the inclined surface 17 until said roller slips over the end into contact with the inclined surface 16, in which position it will remain to hold the gate against tilting until disturbed by the cord 18 or by other means.

I claim- 1. The combination with a tilting gate, of a weighted lever connected to the gate, and

carried by the lever and bearing upon the gate, and means for throwing the catch into and out of contact with the gate.

In testimony that I claim the foregoing as :5 my own I have hereto affixed my signature in the presence of two witnesses.
